Mares & Dow Construction & Skylights installed a large Velux skylight for me in August 2017. The entire experience was wonderful and the skylight is beautiful, both functionally and aesthetically. Janet made sure the work was scheduled to be completed before a trip I had planned. Jimmy measured carefully when he quoted the work and even accommodated a last minute change on the location when he arrived to do the work. They protected my new floors and were careful to keep dust to a minimum. Archie came by to ensure that all was going smoothly. Freddy helped matched the stain on my nearly 70 year old tongue and grove ceiling that really took some effort and he even matched some a few small spots that a previous contractor had sanded and removed the original stain. EVERYONE was cheerful and knowledgeable. Now, my little mid century house has emerged into the light!
Mares & Dow Construction & Skylights replaced two aging skylights in our bedroom and installed automatic blinds on four skylights. This was not an easy job, since our bedroom has very very high cathedral ceilings. In fact, one other skylight installer refused to do the job altogether, and a second made a bid that was almost twice as expensive as Mares & Dow Construction & Skylights. Janet Mares, who was our main contact for the job, was a pleasure to work with. Her son, Jimmy, who led the installation, was fearless climbing the ceiling, and he eally knew his stuff. We’re thrilled with our new and improved skylights, and we appreciate Mares & Dow Construction & Skylights’ solid, reasonably priced, work. Thanks guys!
I’ve had Mares & Dow Construction & Skylights install 3 sun tunnels in my home and most recently, 2 skylights in my garage/art studio. I couldn’t be more satisfied with the quality of their work and professionalism! All my communications with their office and installers have been extremely pleasant. I would use them again (and again) and highly recommend them to anyone looking to install Velux skylights/sun tunnels in their home!
Being a new homeowner, i really did my research before having someone come out and give me a quote on a skylight. You never know what to believe when you read yelp reviews. So, i went ahead and had Jimmy from mares and dow come out and give me an estimate. He was right on time, came out and measured and was very professional while he was here. Janet called me a few days later and sent me over an estimate. I went them them and couldn’t be happier. It arrived in the time frame she had told me, and they were out that week. The workers came out on time, and were very friendly and professional. Dennis ( one of the owners) came out as well and checked on the job. The went above and beyond with their work. The skylight looks beautiful! Night and day from the old one. If you are wanting a skylight, i strongly reccomend going with mare and dow
We had Mares & Dow Construction & Skylights install a Velux skylight in our new master bathroom. The space was small and dark, so Mares & Dow Construction & Skylights suggested a big skylight to add in lots of natural light. They built in a double crown molding to beautifully frame the skylight, and now the space is open and airy with wonderful natural light. We can open the skylight during warm months to let in fresh air. It was a superb addition to our bathroom renovation and a great suggestion from Mares & Dow Construction & Skylights. They did a fantastic job and were great to work with! Thanks guys!

Homes in Benicia, CA experience foundation challenges due to expansive clay soils, seasonal moisture changes, and seismic activity common throughout Solano County. Left unaddressed, foundation issues can lead to serious structural damage and costly repairs. Mares & Dow Construction & Skylights provides professional concrete foundation repair services in Benicia, helping homeowners restore stability and protect their investment.
Benicia homeowners often notice cracks in concrete slabs or interior walls, uneven or sloping floors, sticking doors or windows, and gaps around door frames. Older homes in Benicia may also experience settlement due to outdated construction methods and shifting soil conditions.
Our process begins with a comprehensive foundation inspection to identify the cause of movement or damage. Based on site conditions, we may recommend foundation pier installation, slab leveling, crack repair, or structural reinforcement to stabilize your foundation and prevent future issues.
Benicia’s clay-rich soils expand when wet and contract during dry seasons, placing stress on concrete foundations. Combined with rainfall patterns, hillside terrain, and seismic activity, these factors make professional foundation repair especially important for long-term stability.
Yes. Many foundation issues in Benicia are related to water infiltration or poor drainage. Along with structural repairs, we often recommend grading corrections, French drains, or waterproofing solutions to manage moisture and reduce soil movement around the foundation.
Minor repairs, such as crack stabilization, may take one to two days, while larger projects like piering or slab leveling may take several days to a week, depending on property access and soil conditions. We provide clear timelines before work begins.
Costs vary based on the extent of foundation damage, size of the structure, repair method, and site accessibility. We offer transparent, detailed estimates so Benicia homeowners understand the scope and cost of repairs upfront.
In most cases, yes. Our experienced team works to minimize disruption, allowing homeowners to remain in their homes throughout the repair process. Some areas may be temporarily restricted for safety during active repairs.
Mares & Dow Construction & Skylights brings local expertise, certified professionals, and extensive experience with Benicia’s soil and environmental conditions. We use proven repair methods, comply with California building codes, and stand behind our workmanship to deliver long-lasting results.
